LU-2887 tests: disable SLOW for ZFS in parallel-scale

Because all zfs pools are on the same physical device in autotest
ZFS backed OSTs run VERY slowly so disable SLOW. Decrease load on zfs
backed MDS.

This patch also allows overriding all variables that are set lower
due to SLOW=no, which is forced for ZFS tests.  This will allow values
specified by caller for all variables even when testing on ZFS.

The patch is back-ported from the following two patches:
